2 Claims. (01.22941) This Invention relates to cartons, and morespecifically to folding cartons of the type including scored fold lineson the end and bottom wall panels so that they may be expanded readilyfrom'iiat to set-up position.

.There are many products requirin the protection against injur afforded"by a paperboard carton which have heretofore. been packed in In manyinstances, these products are Fi 3 in set-up condition ready for theinsertion of the product to be packed therein.

In one of its broad aspects my invention comprises a cartonformed from asingle blank of foldable paperboard, having its panels arranged asshownin F-ig'. 1 sothat the glue strip on each end wall panel attached to oneof the'side wall panels overlaps and is secured by an adhesive "to theother of the side wall panels, and

including score lines dividing the bottom and end wall panels intosubstantially equal portions, although the invention is not limited tothe form shown, which has slightly tapered or inclined products oi. thistype. In addition, it is characterized by extreme simplicity and ease ofmanug'reatest facility. One-product in the packaging of which the'carton' of my invention has been found particularly useful isammunition for various types of rifles and other small arms. In the caseof ammunition in the form of clips, it is desirable that the carton beslightly tapered so that one or more such clips will fit snugly into thecarton,'and-my invention is especially advantageous when embodied insuch a tapered carton.

It is an object of my invention to rovide a side and end walls, it willbe described in connection therewith, since it will be obvious to thoseskilled in the art that a similar arrangement of panels and a similarmethod of production can be used advantageously in a carton having auniform rectangular cross-section and rectangu- "iacture and it can beset up for use with the carton ortubular wrapper which is simple,inexpensive and easy to handle from the standpoint of both themanufacturer and the user. Another object is to provide 'a carton ofthis type having a tapered. form so arranged that the inclination of theside walls does'not in any way-hinder the use or conventional automaticgluing equipment of the simplest type for its manufacture. Otherobjects, advantages and uses of my invention will become apparent fromthe. following detailed description which should be readin conjunctionwith the drawing iorming apart thereof. In the drawing:

-Flg. 1 illustrates the blank of a carton accord ing to my invention,thisparticularembodiment thereof being of tapered form adapted toreceive two clips of ammunition;

Fig. 2 illustrates the-carton of Fig. 1 after the first foldingoperation and after the glue has ,beenapplied prepa atory-to the secondfolding operation;

Fig. 3 shows the carton of Fig. 1 .after the second folding operationand after it has been partially expanded; and

Fig. 4 is a perspective view of the carton of lar side and end wallpanels.

Referring first to Fig. 1, the carton blank there illustrated includes apair of substantially'similar side wall panels i0 and H, which are inthe shape of isosceles trapezoids, having their shorter parallel edgesattached to opposite edges of a substantially rectangular bottom panel.I2 along score lines l3 and M, respectively. Extending laterally fromthe side wall panel in along score lines l5 and ii are two end wallpanels I! and I8 which are also substantially isosceles trapezoids inconfiguration, and these side wall panels are in turn Joined along theirother lateral edges l9 and 20 to glue flaps 2i and 22, respectively. Theouter tree edges 23 of glue flaps 2| and 22 are preferably substantiallyparallel in order to facilitate the application of glue as will bebrought out below. Bottom wall panel I! is pro panels; The production ofa blank havingthis configuration and including these score lines is avery easy matter using the technique and equipment customarily used inthe folding carton industry.

The next step involves the folding of panel H over upon side wall l0along score line 2, and

this operation can also be carried out very easily on a conventionalfolding machine by feeding the blanks in either or the directionsindicated" by the arrows in Fig. 1; although it can be done by hand orby the use of more involved equipmam. this foldingoperation has beencompleted, the carton appears as shown in Fig.

parallel relation facilitates the application of I adhesive, althoughglue flaps of substantially different shape can be used and the adhesiveapplied by aconventional timed gluing machine.

Finally, the glue flaps 2i and 22 are folded along score lines 25 and 26so that they overlap the side wall panel H, and the carton is maintainedin this position until the adhesive had set.

- Ordinarily, this folding is done on the gluing machine and presents nodifficulty in practice. v The cartonsare then ready for storage andshipment,

and when it is desired to use them it is only necessary toexert pressurealong score lines 24, 25 and 26 and the carton will expand to theposition' shown in Fig. 3. Continued pressure will further expand thecarton and cause it to 9.3- sume theset-up position illustrated in Fig.4, in

which it is adapted to receive the product to be packed; c

It will be apparent that many modifications in accordance with myinvention can be made by those skilled in the art, without departingfrom the spirit thereof, and it is equally apparent that other methodscan be used in assembling the same. For instance, the glue flaps 2i and22 can be folded over the side wall panel it and the side wall panel Hfolded upon them subsequently to give a carton of substantially the sameconfiguration, but presenting a somewhat more finished externalappearance. Also, it is obvious that the so-called right angle gluingmachine is particularly adapted to manufacture cartons according to myinvention. I do not, therefore, wish to be. limited to the specificembodiment of my invention hereinbefore described, but only by the scopeof'the appended claims.

I claim:

1. A carton or protector formed from a single blank of foldablepaperboard comprising a sub-' stantially rectangular bottom panel, twoside wall panels of substantially isosceles trapezoidal shape havingtheir relatively short parallel edges hingedly attached to oppositeedges of said bottom panel, a pair of end Wall panels hingedly attachedto the non-parallel edges of one of said side wall panels, and a gluestrip attached to the edge of each 01' said end wall panels opposite toone of said non-paralleledges, said bottom panel and said end wallpanels having fold lines there in whereby each of said glue strips canbe folded into overlapping relationship with the other of said side wallpanels and secured thereto \by means of an adhesive, and 'said gluestrips being widest at their lower endsand having their 'free side edgessubstantially parallel to each other I when said carton is in blankform, whereby the 1 application of adhesive theretoin an untimedautomatic operation is facilitated, I

2'. A carton according to claim 1 wherein each of said end wall panelsis of substantially isos-- celes, trapezoidal shapeand has itsrelatively-nan; row portion adjacent the relatively narrow 'portion ofthe side wall panel attached thereto. i
